tubes were obtained off the coast of New York at the depth 

 of 1240 fathoms ^, but, like those of the present collection, 

 they were empty. 



Family CirratulidaB. 



Genus Ch^TOZONE, Mahngren. 



Chcetozone noi'vegica. 



At Station 41 B, lat. m° 42' N., long. 0° 35' E., and at a 

 depth of 75 m., a small complete form about a quarter of an 

 inch in length was dredged. The feet, bristles, and general 

 body-characters are quite diagnostic of the species, and there 

 is nothing of outstanding interest about the form. The 

 bristles are very slender, finely tapered, and almost trans- 

 parent. The animal is not mature. 



This genus is usually found in deep water, while the genus 

 Cirratulus frequents shallower depths. In the ' Challenger ' 

 Report one member of the genus Chcetozone, viz. Chcelozone 

 hent/mliana, was found as deep aa 1250 fathoms, while other 

 representatives were procured at depths varying from 400 to 

 700 fathoms. The species Chcetozone setosa described by 

 Malmgreu was found at a depth of 20-40 orgyiar. 



Family Spionidae. 



Genus SCOLECOLEPIS. 



Scolecolepis vulgaris, Johnston. 



This species is the only representative of the Spionidse. 

 The members of the family are found in greater number in 

 shallow water than in deep water, and in this present collec- 

 tion there are two fragments, each about 1 inch long, showing 

 neither head nor tail. The fragments were obtained in 

 haul 174 with a small trawl on 24tli August, 1908, at 

 Station 19 A, lat. 60° 36' N., long. 4° 46' W., and at a depth 

 of 1030 m. This depth is the greatest which has as yet 

 occurred in the data of the hauls connected with the Scotch 

 North Sea investigations ; but in the * Challenger ' Report 

 members of the family were dredged at depths ranging from 

 110-725 fathoms. In the account of this species given by 

 M'Intosh t no depth is given, and in Izuka^s work on the 

 Errantiate Polychseta of Japan the Spionidse do not even 

 occur.
